Orbi DMZ not working?

[SkywalkerPD]

I can't seem to get my DMZ configuration to work on my Orbi RBK50?

Before I had a ASUS RT-AC66U put the internal address of my NAS in the DMZ settings and it worked. With the Orbi I did the same. Put the internal address of my NAS in the DMZ settings and applied the settings. But it is impossible to use any of the internal features...

Can't connect to Synology DMS, NFS, FTP etc. nothing seems to work.

Please advise?

Trying to connect from an external connection shows me this...

I would suggest manually forwarding only the ports you need opened to the Internet. This is more secure than a DMZ.

[SkywalkerPD]

That is good advise! I think I will do so, but this was to test if I could connect externally.

Would you advise port forwarding or port triggering?

Forwarding.  From the port you posted it looks like you have a Synology. I use forwarding for my Synology. I’ve never had to use triggering for anything.
